Notice of the 44th "Latest Construction Method and Technology Training Seminar"

I would like to report on a new initiative that utilizes the cutting function of steel obstacles.

Yasuda Engineering Co., Ltd. will conduct a seminar at the 44th "Latest Construction Technology Seminar on Advanced Propulsion Methods" held in Tokyo and Osaka. We will report on our new initiatives utilizing the steel obstacle cutting function of the milling mole method. This seminar is accredited as a "Continuing Professional Development (CPD) Program" by the Japan Society of Civil Engineers. (CPD credits: 6.5) We sincerely look forward to your attendance. [Overview] ■ Seminar Time: 14:55 - 15:50 ■ Seminar Content: Challenging New Areas with the Milling Mole Method - New Initiatives Utilizing the Steel Obstacle Cutting Function - *For application details, please refer to [Details on How to Apply for Participation Here]. *For more information, please refer to the PDF document or feel free to contact us.

It is possible to directly reach the existing shield through the application of metal cutting technology! We are currently presenting examples of construction where direct cutting was performed on existing shields.

The "Milling Mole Method" is equipped with a specialized bit designed for cutting through obstacles using a tunneling machine. It allows the cutter of the tunneling machine to make ultra-low-speed contact with obstacles through a special telescopic pipe, enabling cutting through the rotation of the cutter. This operates on the same principle as lathe machining. A significant feature of this construction using the "Milling Mole Method" is that it achieved direct cutting of steel segments without performing mirror cutting. Since improvements to the protective measures of the existing shield section could not be made from the surface, a boring machine was mounted, allowing for injection from within the tunneling machine (using a dual-pipe strainer method with multiple phases). Additionally, a formwork for cutting connection was installed inside the existing shield, and fluidized treatment soil was placed, allowing for direct cutting at ultra-low speeds and safely avoiding the risks of water inflow and subsidence accidents that occur during mirror cutting. Previously, mirror cutting was performed from within the shield, raising concerns from customers about the risks to the surrounding environment due to groundwater inflow and ground collapse associated with that construction. We proposed direct cutting of the existing shield, and after executing the construction, we successfully reached the target without affecting water inflow or the surrounding environment, resulting in great satisfaction from the client! 《You can download the construction case from the PDF below!》

Introducing a case study of shield arrival construction using the milling mall method!

The "Milling Mole Method," equipped with four special functions: exploration, improvement, cutting, and guidance, is a ground obstacle response type mud-based thrusting method. It consists of three devices: a tunneling machine, a special telescopic pipe, and a special injection pipe, allowing for the precise cutting and removal of underground obstacles. In the construction of the inflow pipe sewer system for the second Nakagawa Chubu rainwater adjustment pond, the Milling Mole Method was used to carry out the shield arrival work. Milling cutting length: The assembly precision of the steel formwork at the arrival section inside the existing shield, L=1.520m from the outer circumference of the existing shield, was excellent, and there were no leaks of groundwater or muddy water during the placement of fluidized treated soil or during the shield cutting with the tunneling machine, allowing for safe cutting. 【Construction Example】 ■Location: Nagoya City, Aichi Prefecture ■Client: Nagoya City Waterworks Bureau ■Contractor: Asanuma Corporation ■Nominal Diameter: φ2200mm ■Thrusting Length: 101.520m ■Underground Obstacles: Direct access to the existing shield Inner diameter of the existing shield φ3750mm *For more details, please refer to the PDF document or feel free to contact us.

In the field of food and health food research and development, an increasing number of companies are facing the following challenges: - Difficulty in exploring new functional materials and differentiation themes, leading to a depletion of research topics. - While they are collecting information from conferences and papers, they struggle to translate this into research themes directly related to their products. - They remain limited to competing similar products and follow-up projects, failing to establish uniqueness. - Although there are seeds of ideas, they struggle to elevate them to scientific hypotheses and build the necessary foundations for internal approval. Behind this lies a "wall of execution" that cannot be overcome by traditional information gathering and research processes. In this webinar, we will introduce a new R&D approach to break through these challenges. It is a next-generation research and development scheme that combines AI-driven hypothesis generation, which has achieved results in drug discovery, with scientific hypothesis verification by a food human trial CRO. This will allow for the transformation of vague ideas into scientifically verifiable projects, simultaneously achieving the construction of persuasive foundations for upper management and differentiation development.

Fujikohsuhou Industrial Co., Ltd. will hold an online seminar titled "Tips for Setting Laser Hardening Conditions" on July 20, 2025 (Wednesday). In laser hardening, factors such as output and speed are related to the quality of hardening. We will explain how output and speed are connected to quality factors. This seminar is aimed at those who are looking to start utilizing laser hardening. 【Recommended for】 ■ Those who want to learn about methods for setting laser hardening conditions ■ Those who want to obtain technical information about laser hardening

Take the 'first step' in DX talent development in Fukuoka. We will hold a free seminar where you can learn reskilling strategies that can be applied in the field through case studies and experiences! 'I've become responsible for DX, but I don't know where to start.' This is a participatory seminar aimed at representatives from small and medium-sized enterprises in Fukuoka City, Fukuoka Prefecture, where you can learn the 'first steps' in DX talent development and implementation support. While introducing case studies of representative DX tools such as Power Automate and Power BI, you will experience hands-on sessions with Copilot, allowing you to grasp practical small-start methods that can be implemented on-site. The content also includes specific success stories from the Fukuoka region, along with tips for promoting understanding and advancement within your organization.

We will be exhibiting at INCHEM TOKYO 2025, which will be held at Tokyo Big Sight from September 17 (Wednesday) to September 19 (Friday). This time, we will host many events, including special project stages and mini-seminars. At our booth, we will introduce our solutions and technologies based on the theme of "Sustainable Plant Engineering" from three different concepts. Please be sure to stop by our booth, East Hall 6, K-17.

The Siemens EDA Tech Forum is a technical event aimed at sharing the latest technological trends, case studies, and solutions to challenges with everyone involved in the design and development of silicon systems and electronic systems, while addressing evolving technologies, the densification and complexity of designs, and various design challenges, all while meeting requirements for quality, safety, and reliability. The goal is to deepen insights and networks towards achieving sustainable business. The forum covers a wide range of topics, from advanced design technologies and methods in fields such as 3D ICs, chiplets, chips for AI and ML (machine learning), and IC packaging, to the design, analysis, and collaborative development of electronic systems, including printed circuit boards, across multiple domains, as well as building ecosystems both internally and externally using digital threads. Through case presentations and explanations of design methods by industry leaders, it supports solutions to challenges faced in daily design work from all directions.
